- MathiasPius 3y agoI haven't had an excuse to test it yet, but since it's only 6 OSDs across 3 nodes and all of them are spinning rust, I'd be surprised if performance was amazing. I'm definitely curious to find out though, so I'll run some tests and get back to you!
- MathiasPius 3y agoI rand rados benchmarks and it seems writes are about 74MB/s, whereas both random and sequential reads are running at about 130MB/s, which is about wire speed given the 1Gbit/s NICs.
